To see the parameters available in the input panel, select the Building layer in the Navigation Tree. You'll then see the input panel populate. ### Residential High Density Example: ![manipulating buildings 01](https://support.testfit.io/hs-fs/hubfs/CS%20-%20Customer%20Success/CS%20-%20Knowledge%20Base/CS%20-%20Knowledge%20Base/Building/manipulating%20buildings%2001.jpeg?width=438&height=1043&name=manipulating%20buildings%2001.jpeg) ### Industrial Warehouse Example: ![manipulating buildings 04](https://support.testfit.io/hs-fs/hubfs/CS%20-%20Customer%20Success/CS%20-%20Knowledge%20Base/CS%20-%20Knowledge%20Base/Building/manipulating%20buildings%2004.jpeg?width=670&height=503&name=manipulating%20buildings%2004.jpeg) --- #### Sub-layers If the Building layer has sub-layers, you can also click on those to see what parameters are available there. ![manipulating buildings 02](https://support.testfit.io/hs-fs/hubfs/CS%20-%20Customer%20Success/CS%20-%20Knowledge%20Base/CS%20-%20Knowledge%20Base/Building/manipulating%20buildings%2002.jpeg?width=438&height=1179&name=manipulating%20buildings%2002.jpeg)   --- ### Unit Editors You can also adjust a residential building, by changing the units that TestFit is placing in the [High](https://support.testfit.io/knowledge/unit-editor?hsLang=en) or [Low Density Unit Editor](https://support.testfit.io/knowledge/lower-density-unit-editor?hsLang=en). --- ### Manual Mode [Manual Mode](https://support.testfit.io/knowledge/manual-mode?hsLang=en) allows you to modify the geometry generated by TestFit by converting it into an editable skeleton.   -
